THREAD-GUIDE SU PPORT.

Beit known that I, VILLIAM O. ALDRIGH, a citizen of the United States, residing at VVhi-` tinsville, in the county o't' Worcester and State 5 of Massachusetts, have invented a new and useful Improvement in` Thread-Guide Supports for Spinning or Twisting Machines, oi' which the 'following is a-speciiication.

This invention has reference to an improvement in the construction oi sheet-metal thread-guide supports for spinning or twisting machines.

In spinning or twisting machines the threadguide supports usually consist of iinger- I 5 boards carrying guide-eyes and iinger-board heads hinged to the side bars of the machine and pivotally supporting the Enger-boards.

The object of my invention is to improve the construction oi' sheet-metal linger-boards 2O and finger-board heads and by this improved construction to hold the iinger-boards in their normal or turned-down position more iirmly than has heretofore been done.

A further object oi`-my invention is to hold 2 5' the guide-eyes as rigidly as possible, and I accomplish this object by forming the stop or support for the linger-board centrally on a line with the guide-eye and strengthen the support by stamping up ribs on the support the guide-eye stem.

My invention consists in the peculiar and novel construction of the finger-board and the iinger-board head, as will be more fully set forth hereinafter.

Figure l is a top plan view of my improved thread-guide support detachedy Jfrom the side bar oi' the machine, showing all but two of the finger-boards and adjacent finger-board 40 head broken away to clearly show my invention. Fig. 2 is a plan view looking at the under side of one of the finger-boards and adjacent portion of the iinger-board head.

' Fig. 3 is a vertical sectional view taken on line X X of Fig. 1, showing the iinger-board in the turned-down position and the means of securing the linger-board head to the side bar of the machine. Fig. 4 1s a vertical detail PATENT OFFICE.

head, showing the leat` of the hinge raised to clearly show the construction of the hinge. Fig. jis a detail sectional view taken on line YY of Fig. 1i, showing the parts of the hinges formed integral with the iinger-board and iinger-board head; and Fig. 6 is an enlarged 55 vertical sectional view similar to Fig. 3, showing the finger-board in the turned-upposition for dofiing the bobbin.

In the drawings, c indicates the side bar of a spinning-frame; b, the iingcr-board head; lc c, the Enger-boards, and cl (Z the guide-eyes. The {finger-board head is stamped or pressed Jfrom sheet metal to form integral the i'lat top the back b2, the closed ends 7) L, in which are the holes b b", and the hinge-knuc- 6 5 kies if If andG bf. The knuckles b5 b'r on the front are formed by rolling outwardly-extending tongues over to form a cylindrical knuckle, and the knuckles L b are Jformed by cutting the tongues from the back b2, bending them upward, and forming them into the cylindrical knuckles, as shown in Figs. i and 5.

and the knuckle If on the butt bs to Jorm a hinge, which is secured to the side bar c of the machine by screws in the usual way.

The iinger-board head Z) is preferably made in sections supporting ten or twelve {ingerboards and may be secured together by bolts through the holes L* l in the ends b3 If; but, ii' desired, they could be made in one continuous piece extending the entire length oitl the machine.

The iinger-boards c c are stamped from sheet metal to form integral the liat body portion c', the downwardly-extending lip c2 on the front, in which is the notch c3 for the guide-eye stem,the hinge-kn uckles cIl c", formed from tongues on the body portion c', and the hook-shaped inwardly-extending arm c5, with the stam pcd-up strengthening-ribs cG c, adapted to extend centrally under and bear on the under side oil the iingcr-board head b to form a stop and hold the linger-board in its normal or turned-down position, as shown in Fig. 3. 9 5

The knuckles cl cAL cooperate with the wire pintle o7 and the knuckle 2f to form a hinge pivo tally connecting the linger-board with the linger-board head. The strengthening-ri bs c6 c extend forward on the under side ol' the finger-board and stiflen the same. The wire guide-eye (Z has the shank fl', on the outer end of which is the usual coil, forming the c ve d". The inner end d is bent approximately T- shaped to prevent the shank turning under the clamp d", secured to the u nder side of the linger-board by the boltfZl, as shown in Fig. 2.

In the use ot' my improved sheet-metal thread-guide supports the linger-boards are supported and stilfened centrally and the guide-eyes more firmly held in their operative positions by this central supporting and still'- ening of the linger-boards than has heretofore been done.

Having thus described claim as new and Patent` 1. lin a thread-guide support for spinning or twisting machines, a sheet-metal lingermy invention, I desire to secure by Letters board head having flanges forming a back and ends, parts formed integral with the lingerboard head coperating with pintlcs and butts to form hinges on the back of the lin ger-board head, sheet-metal linger-boards, parts formed integral with the linger-boanls and lingerboard heads cooperating with pintles to form hinges connecting the linger-boards with lhe linger-board heads, means lor supporting the linger-boards in their turned-down position consistingol' a central arm on the linger-beim ls adapted to extend under :1nd der side olE the linger-board stillening the central arm und linger-luiurds consistingot' ribs on the arm :md linger-lmurd extending centrally toward the lront oll the linger-board, and means ing guide-eyes to the linger-boards, as described.
